Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Im gmt -6. 10 pm your time would be 2 pm my time, whichc would be a little awkward for me because I will be at work. I normally eat lunch closer to 1 pm, would you be ok doing 9 pm your time on either of those days?
Hey man do you mind playing 2h later? (I.e. 11pm gmt+2) something made me unavailable at the time we scheduled, if you can't I can play later again (3am gmt+2 would be still ok) or we can play tomorrow same hour (9pm gmt+2)
I unfortunately am going to be running an experiment during that time, and I won't be able to play at 3 am your time either (also making you play at 3 am doesn't seem very fair to you). Lets do 9 pm your time tomorrow.
